Mattel Hot Wheels^® Color Reveal^™ 2-Pack Cars

This pack of two color-reveal cars is loaded with awesome surprises and is perfect for gift giving. First, fill the drum with water and swirl each car around in it until the water changes color, then pull the car out—the sweet decos hiding underneath are exposed. If you want the vehicle to change color again, fill the drum with cold water and dunk each car in for yet another awesome transformation. Change it back by dunking it in warm water.
